Flexible alkaline battery

Abstract

This invention presents the development of flexible battery especially primary and secondary alkaline batteries. Nano carbons, in particularly carbon nanotubes are implemented in conductive polymers to develop flexible electrodes. Polymer separators that can withstand high pH and serve the purpose of electrolyte storage is used to enhance performance. The relatively inexpensive multiwall nanotubes represent are effective ingredients in development of flexible electrodes.
